Not a silly question at all -- indeed a natural one for a new member to pose. For that reason, answers to many recurring questions about our Community are collected in a master thread that is "stuck" near the top of this CommunityBuzz list of threads. The particular thread which will answer your question at length is at

As the above thread is so comprehensive, I'll close this one now, with the hope that you will be able to join -- or even host -- a FT 'do in the future. Ocn Vw 1K, Co-Moderator, CommunityBuzz
